Projector and projection method

Abstract

The invention discloses a projector and a projection method. The projection method is applied to the projector. The projector comprises a central processing unit, as well as a first WiFi (wireless fidelity) communication unit and a second WiFi communication unit, which are connected with the central processing unit. The projection method comprises the following steps: the first WiFi communication unit receives projection data uploaded by one or more first terminals through a wireless network; the central processing unit controls the second WiFi communication unit to send the projection data to one or more second terminals. According to the projector and the projection method, by the projector, the projection data uploaded by the first terminal(s) can be received through the wireless network, and the projection data can also be sent to the second terminal(s); the projection data is uploaded more conveniently; moreover, projected contents can be directly watched on the terminal(s), and can be watched more favorably.

Description

technical field [0001] The invention relates to the field of projectors, in particular to a projector and a projection method. Background technique [0002] The projector is one of the essential equipment in various conferences, but most of the general-purpose projectors used now still have a VGA (Video Graphics Array) interface. If it is a device without a VGA output interface (such as an Apple notebook), It must be connected to the projector through an adapter cable (such as HDMI to VGA), so as to output the content to be projected to the projector. [0003] Because the projector can only be connected to one terminal at a time, if multiple people in the meeting need to use the projector alternately, the VGA cable of the projector must be plugged and unplugged among several terminals; or a terminal is fixed to output to the projector. Several people alternately use the terminal by swapping places; either way, it's extremely cumbersome to use. [0004] Moreover, the existi...

Problems solved by technology

[0003] Because the projector can only be connected to one terminal at a time, if multiple people in the meeting need to use the projector alternately, the VGA cable of the projector must be plugged and unplugged among several terminals; or a terminal is fixed to output to the projector. Several people use the terminal alternately by swapping places; either way, it's extremely cumbersome to use

[0004] Moreover, the existing projectors do not have a download function. When other people participating in the meeting feel that the projected content is of interest to them or they think it is particularly important, they can only take pictures with their mobile phones or download them after the meeting. , taking pictures not only affects other participants, but also subject to objective factors such as distance and light, the effect of taking pictures will not be ideal; and there is often not much time to download files for participants after the meeting

[0005] There are also some participants who cannot see the projected content clearly because their positions are too far away from the projection screen, the angle is too biased, or their own eyesight, etc., and it is urgent to solve this problem
